|Abstract:||Global Navigation Satellite System (GNSS) jammers are small portable devices capable of transmitting powerful electromagnetic waves, which can easily disrupt GNSS signal reception over a wide geographical area. The first line of defence against GNSS jamming is the early detection of jamming signals. In this paper, the problem of model-based jamming detection is considered. In particular, a piece-wise linear model is developed to describe the frequency evolution of a jamming signal. This model is then used to design the Piece-wise Linear frequency Detector (PLD). The PLD is compared with the energy detector and with the Cyclostationary Feature Detector (CFD) that exploits the periodicity of mean of the jamming signal. Theoretical analysis and experiments involving real jammers show the benefits and drawbacks of the different approaches considered.|
